[SOLVED] firewall on and no monitor access

So I ignored all the warnings while messing around with proxmox's firewall and turned on the datacenter's firewall with it's default DROP.
I have one gpu that I set up a while back for gpu passthrough, so if I recall, that gpu doesn't get allocated by pve so that it's "saved" for the windows vm.

I have a monitor and a mouse, but realistically what are my options to regaining access to my web-ui? Is there a way to halt the boot process before pve drops the gpu, allowing access to the terminal?

for reference these are my current boot flags:
Code:
ro quiet amd_iommu=on textonly video=astdrmfb video=efifb:off initcall_blacklist=sysfb_init

when i remove all of those, my keyboard disconnects during boot, and proxmox appears to hang on this:
Code:
vfio-pci 0000:0b:00.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=none:owns=none```
which leads me to believe vfio is grabbing all my devices.

if anyone runs into this in the future with those boot flags here's what I did:
removed quiet amd_iommu=on textonly video=astdrmfb video=efifb:off initcall_blacklist=sysfb_init and added

modprobe.blacklist=vfio,vfio_iommu_type1,vfio_pci
